FAQs
Will this rear diffuser lip fit my Audi S4 A4 B9?
It matches the rear bumper shown in the gallery for 2017-2019. Compare the valance shape in the photos with your own bumper first.
Is the carbon real?
Yes – carbon fiber with a UV-stable clear coat. Not a hydro-dipped or printed finish.
Do I need to cut the rear bumper?
No. It replaces the factory lower valance section and uses the original mounting points.
Does it come with fittings?
The piece itself is supplied as shown; the factory fixings on your car are reused. Tape or sealant is recommended by most installers.
How long does production take?
Around 10-15 business days because each piece is made to order, then shipping with tracking.
